Just bought a eprom ecu for my 2g. I took of battery cable, then removed the stock ecu and installed the eprom ecu, then hooked battery cable back on. Went to start the car and it turns but never starts. I then reversed everything and put stock ecu back in and car started fine. Then i installed the eprom again and took off the plugs to the injectors and went to start it and still turns but never starts. Plugged the injector plugs back in and tryed to start the car and it turns but never starts. Any clue on why the car will not start up?

Would the stock 1998 alarm have anything to do with the stock ecu and eprom ecu?
just trying to bounce some ideas of you guys to try and figure out why the eprom isnt letting me start the car

The motor is a 6 bolt btw
